IMPROVEMENT IN DEVICES FOR APPLYING POWER FROM A ROTATING SHAFT T0 A LASTING-MACHINE.

Specication forming part of Letters Patent No. 213,857, dated April 1, 1879; application filed December 6, 1878.

To all whom it may concern.-

Beit known that we, ERAsTUs WoonwARD and MATTHIAs BROCK, both of Boston, in the county of SuEolk, and in the Commonwealth of Massachusetts, have invented au Improvement in Devices for Applying Power from a Rotating Shaft to Lasting-Machines, of which the following is a specication:

This invention relates to appliances in and connected with a lasting-machine, serving to control and operate the moving tools thereof from a rotating shaft.

Patents previouslyT granted fully set forth the movements of the cross-head and the movements of the jaws which support the girth-carrying ngers upon the cross-head. The motions necessary to give to the girthsupporting iin gers are substantially these: an upward vertical movement parallel, or substantially parallel, with the sides of the last toa position somewhat above the plane of the upper surface of the insole, followed by a closing-movement, which shall cause the ends of the fingers to-project upon the surface of the insole, and an inwardly-descending movement to said surface. These movements or modifications thereof are necessary in wrapping a girth upon the surface of the last in the lasting process. To remove the lasted upper from the machine, and to return the girth and girthactuating mechanism to its original position preparatory to their again operating, it is necessary that these movements of the girth-carrying lingers be reversed; and our improvement consists in automatic means for providing the girth-carrying iin gers with these movements, and in automatic devices for controlling their operation when power is employed in running the machine.

tinctly show the construction and operation of certain parts not clearly shown in the other views. Figs. 6 and 7 further illustrate the construction.

The cross-head A is provided with a vertical movement within the frame B by means of the cam-groove C in the face of the disk c, the connecting mechanism being a yoke, c1, which straddles the support c2, and whose inner and outer faces c3 act as guides, in connection with the surfaces c4 of said support c2 and the surface c5 and the face of the disk c, in guiding said yoke in its vertical movement and the rod D.

The rod D is provided with the ri ght-and-left screwsdd. The ends ofsaid connecting-rod are screwed into nuts c6 and a upon the yoke and cross-head respectively. The movements of the cross-head are thus controlled by the camgroove C, and by varying the position of the groove more or less' throw can be given the cross-head.

The cross-head, it will be observed, is provided with an upward movement, a stationary period, and a slight falling movement. This movement, ofcourse, can be varied by changing the location of the cam-groove. The height to which the cross-head lifts may be adjusted by means of the screw connecting-rod D, by increasing or diminishing the space between the yoke and the cross-head.

The cross-head is provided with suitable extensions al upon each s'ide, which slide in corresponding ways b in the frame B. The top of the cross-head is provided with a flat table or plate, which extends beyond each side of the cross-head, as shown in Fig. 3, and furnishes the support for the jaws E, which carry the girth-supporting ngers e, and which are provided with horizontal closing and opening movements.

The levers F, pivoted at f to the cross-head, and operated by the cam-groove G in the disk g through a yoke, H, which straddles the support I, and is guided thereon in the same manner that the yoke c1 is guided, the connectingrod K, having right-and-left screws k k', and the sliding plate M, which has a vertical movement upon the cross-head, and is provided with slots m', in which the pins f' upon the lower ends of the levers F close and open the jaws E.

During the upward throw of the cross-head the connecting-rod K and the connecting-rod D move at about the same speed until just before the cross-head reaches the highest point, when the connecting-bar K com mcnccs to move somewhat faster; then the connectingrod D continues its upward movement after the cross-head becomes stationary, thereby lifting the plate M, and causing the same to close, or partly close, the jaws E by spreading the levers F.

Before the jaws are entirely closed the crossliead may fall slightly, which will facilitate their closing. The cross-head A and plate M may then drop a short distance together.

The connecting-rod K maybe used to adjust the distance between the yoke II and the plate M in the same manner that the connecting-rod D is used to regulate the distance between the yoke and the cross-head.

The cam-groove (i, therefore, actnates the mechanism which operates thc horizontal movements of the jaws.

The disks c g, in which the cam-grooves are formed, or upon which they are secured, are fastened. one upon each side, to the driven spur-wheel N. This driven spur-wheel is keyed to the revolving shaft n, which is provided with bearings in thc supports c, I, and n.

The spur-wheel 1N' is driven by the drivingcog 0 upon the, counter-shaft o. Arranged upon this connter-shaft are the loose pulleys l P', which it is intended shall be belted to run in opposite directions. These loose pnl leys are provided with the coneshaped rc ceases p upon their opposite faces. Between the loose pulleys is arranged a pair of coneciutches, R Rl, rigidly united bythe sleeves R2 and the collar R3. The sleeves slide on the fast feather R4 on the shaft n.

The clutches are respectively forced into the interior of the pulleys 1 1l in reversing the movements of the cross-head and jaws by means of the crank S, which lays hold of the pins s, projecting from the collar It, and the lever S.

The dog T raises and lowers the lever S', to automatically disengagc the clutches from the driving-pulleys i m mediately bcforethe reversal of the motion. lt is pivoted at tto thc support c2, and isprovided with arms t' tl, upon whicl|,or upon pins projecting therefrom, the edge-cam V bears in depressing or raising the lever S'. The edge-cam Y is formed on a loose disk, Y', upon the shaft u, and the pin t, which projects from a revolving disk, t", made fast to said shaft n, plays in the slot rl in the loose disk, and causes the same to partially revolve in operating thc dog T.

When the cross-head is in its lowest position the portion of thc cam at e bears upon the arm t and throws the dog to its lowest position,causing it to depress or lower the end of the lever S', and when the portion of the cam ci is reversed, and contacts with the arm t2, the dog T is lifted, thereby raising the end of the lever.

Loosel y attached to the shaft n is the bracket or arm X, the outer edges of which, at .1, arc

caused to alternately engage with the brakewheel Y, rigidly fastenedto the countershaft o.

A collar, x", pinned to the shaft n, and provided with thc projection mz, to contact with the portion x on the brake bracket or arm X, operates the brake by causing the same to bc firmly held against the brake-wheel, and they are so timed that the brake is applied at the limit of the opening and closing movements.

A spring, w, surrounding the shaft n, bears against the outer end of that portion of the bracket surrounding the shaft, and clamps it against the collar in order that the collar, in its revolution, may carry the brake to a position against the brake-wheel before the brake is applied, in order that the same may not be thrown violently against the brakewheel when it is operated.

The cross-head A may be provided with the downwardly-projecting arms or brackets ai, to the lower end of which may be fastened the springs ai, which regulate the tension on the straps or girth a.

The girth or strap supporting fingers e may be pivoted to move vertically in their respective boxes e at c. This gives each linger a longer leverage than has heretofore been given them. The advantages of this mechanism are so obvious that it is not necessary to specitically state them.

The operator lowers the lever S', which causes the coneclntch R to engage with thc pulley P, constantly revolving in the direction indicated by the arrow. The counter-shaft and driving-gear are thus set in motion, and thc cross-head and jaws actuated by the cams.

At the conclusion of the upward and closing movements the lever is automatically lifted, disenga-ging the clutch from the pulley, and the brake is automatically applied. To reverse the movements, the operator lifts the lever S', when the clutch R engages with the pulley P', which constantly revolves in an opposite direction from that of the pulley l, and the brake is automatically thrown olf, and thc jaws opened and cross-head lowered until the cross-head reaches its lowest level, when the. lever is automatically lowered by the dog T, disengaging the clutch Rl from the pulley P', when the brake is again reversed, and again automatically applied, leaving the lever in a position to again move the clutch R.

1t will be observed that when the cross-head is at its lowest level the lever S' can only operate the pulley which lifts the cross-head. The dog T prevents it from heilig lifted suiciently to throw the clutch R against the other pulley. Likewise, when the motions are reversed, in opening the jaws and lowering the crosshead the dog again prevents the lever from being moved in other than the right direction for operating the proper pulley.

It will also be observed that immediately after the mechanism has been started or rcversed the dog ceases to act as a stop, and allows the lever to operate either ofthe clutches, so that at the commencement of the llpward or downward movements the machine can be started only in the right direction, and if once started will automatically come to rest at the end of the respective movements, but'that at any `intermediary stage the machine is under the control of the operator, and the movements can be reversed at any time except at their said commencement.

Although this mechanism is described as employed in operating girth-supporting fingers only, We do not confine ourselves to its use in connection therewith, but may employ it or portions or modifications in actuating any devices for adjusting, tting, and clamping an upper upon a last, or in folding its edge upon the insole in the lasting processes, whenever it is necessary to provide devices for so doing with vertical movements parallel, or substantially parallel, with the `sides of a last, and horizontal closing and opening movements parallel, or substantially parallel, with the plane of the surface of -the insole or any variation or modification of these movements.
